I implemented Azure NotificationHub push notification. I tested for a couple of devices.
It works on these devices:
- Samsung J5 phone Android 7.1.1 (API 25)
- Samsung Tablet A Android 7.1.1 (API 25)
But no push notification is received on a Samsung S9 phone running Android 8.0.0 (API 26)
What could be wrong with the Samsung S9?
